Problems solved by technology

[0003] Due to axial vibrations in the crankshaft, relative movements can occur between clutch and release bearing, especially in clutches with a displacement-controlled wear compensation adjustment, whereby the clutch pressing force can fluctuate and thus , the transmittable torque may fluctuate

Embodiment Construction

[0021] First refer to figure 1 and 2 The friction clutch 1 according to the first exemplary embodiment is shown in partial view. A friction clutch 1, which is designed in particular for use as a starting clutch in a drive train of a motor vehicle, has a pressure plate 2 which is non-rotatable but can be actuated in an axial direction A It is connected with the clutch housing 3 in a limited displacement manner. In this embodiment of the housing 3 in figure 1 The part shown in is the housing cover 4 . Furthermore, the clutch 1 has a disc spring 5 which acts as a compression spring between the pressure plate 2 and the housing 3 and acts in the axial direction A (that is to say in the figure 1 and 2 center down) to load the pressure plate 2 to clamp the clutch disc S (shown only schematically) between the pressure plate 2 and the corresponding plate (not shown). In this case, the disk spring 5 presses in its radially outer region 6 against an adjusting ring V arranged on the...

Abstract

The invention relates to a friction clutch for a drive train of a motor vehicle, having a contact plate, which is connected to a housing in a non-rotatable manner yet with limited axial movement, a disc spring, which is effective between the housing and the contact plate and loads the contact plate in the axial direction in order to clamp a clutch disc between the contact plate and a counter-plate, and a damping arrangement having at least one friction element that has a damping effect on at least axial vibrations of the contact plate and / or of the disc spring, wherein the at least one friction element has a contact region that is in operative engagement with an axial face of the disc spring and / or with an outer edge of the contact plate. The hysteresis of the clutch according to the invention can be increased by relatively simple structural measures and the torque fluctuation can thereby be reduced.

Description

technical field [0001] The invention relates to a friction clutch which can be used in particular as a starting clutch in a drive train of a motor vehicle and by means of which a torque can be transmitted from an input shaft, for example a crankshaft of an engine, to an output shaft, for example a transmission on the input shaft. Background technique [0002] In a starter clutch, as is known, for example, from DE 197 46 281 A1, the torque generated by the motor vehicle engine can be transmitted via a flywheel rotatable about an axis of rotation. A pressure plate for torque transmission is connected to the flywheel, which pressure plate can then frictionally transmit the torque to the clutch disk via the friction lining. [0003] Due to axial vibrations in the crankshaft, relative movements can occur between clutch and release bearing, especially in clutches with a displacement-controlled wear compensation adjustment, whereby the clutch pressing force can fluctuate and thus ...
